<h1 class="title toc-ignore">Installing from Local Sources</h1>



<p>If your project depends on R packages not available in any external source, you can set up an ad-hoc local source to use during restore. This allows you to provide package tarballs that can be used to restore packages otherwise not available elsewhere.</p>
<p>The environment variable <code>RENV_PATHS_LOCAL</code> can be used to customize where this local source of packages should live. It should point to a directory containing package binaries and sources, with a structure of the form:</p>
<ul>
<li><code>${RENV_PATHS_LOCAL}/&lt;package&gt;_&lt;version&gt;.tar.gz</code>; or</li>
<li><code>${RENV_PATHS_LOCAL}/&lt;package&gt;/&lt;package&gt;_&lt;version&gt;.tar.gz</code></li>
</ul>
<p>Alternatively, you can also use project-specific local sources by placing your packages within a folder located at <code>renv/local</code>. Note that this folder does not exist by default; you must create it to opt-in to this mechanism.</p>
<ul>
<li><code>&lt;project&gt;/renv/local/&lt;package&gt;_&lt;version&gt;.tar.gz</code>; or</li>
<li><code>&lt;project&gt;/renv/local/&lt;package&gt;/&lt;package&gt;_&lt;version&gt;.tar.gz</code></li>
</ul>
<p>As an example, if your project depended on a package <code>skeleton 1.0.0</code>, you could place a tarball for this package in one of the following locations:</p>
<ul>
<li><code>${RENV_PATHS_LOCAL}/skeleton_1.0.0.tar.gz</code></li>
<li><code>${RENV_PATHS_LOCAL}/skeleton/skeleton_1.0.0.tar.gz</code></li>
<li><code>&lt;project&gt;/renv/local/skeleton_1.0.0.tar.gz</code>; or</li>
<li><code>&lt;project&gt;/renv/local/skeleton/skeleton_1.0.0.tar.gz</code></li>
</ul>
<p>Once this is done, <code>renv</code> will consult these directories during future attempts to restore packages installed from unknown sources.</p>
<p>To directly install a package from these local sources, you must specify the package version or provide the full path to the tarball:</p>
<ul>
<li><code>renv::install(&quot;&lt;package&gt;@&lt;version&gt;&quot;)</code></li>
<li><code>renv::install(&quot;&lt;project&gt;/renv/local/&lt;package&gt;_&lt;version&gt;.tar.gz&quot;)</code></li>
</ul>
<p>Note that packages placed in one of these local sources will override any default source recorded in the lockfile. For example, if <code>skeleton 1.0.0</code> was also available on CRAN, <code>renv::restore()</code> would still use the locally-provided tarball rather than the version available from CRAN.</p>
<p>If you want to see what directory is being used by <code>renv</code> for local package sources, you can execute:</p>
<div class="sourceCode" id="cb1"><pre class="sourceCode r"><code class="sourceCode r"><span id="cb1-1"><a href="#cb1-1" aria-hidden="true" tabindex="-1"></a>renv<span class="sc">:::</span><span class="fu">renv_paths_local</span>()</span></code></pre></div>
<p>See <code>?paths</code> for more details.</p>
<div id="explicit-sources" class="section level2">
<h2>Explicit Sources</h2>
<p>You can also provide explicit source paths in the lockfile if desired. This is most useful if you are building an <code>renv</code> lockfile “by hand”, or need to tweak an existing lockfile to point at a separate package for installation. For example, you could have a package record in <code>renv.lock</code> of the form:</p>
<pre><code>{
  &quot;Package&quot;: &quot;skeleton&quot;,
  &quot;Version&quot;: &quot;1.0.1&quot;,
  &quot;Source&quot;: &quot;/mnt/r/pkg/skeleton_1.0.1.tar.gz&quot;
}</code></pre>
<p>Packages should have the following extensions, depending on whether the archive contains a binary copy of the package or the package sources:</p>
<table>
<thead>
<tr class="header">
<th><strong>Platform</strong></th>
<th><strong>Binary</strong></th>
<th><strong>Sources</strong></th>
</tr>
</thead>
<tbody>
<tr class="odd">
<td>Windows</td>
<td><code>.zip</code></td>
<td><code>.tar.gz</code></td>
</tr>
<tr class="even">
<td>macOS</td>
<td><code>.tgz</code></td>
<td><code>.tar.gz</code></td>
</tr>
<tr class="odd">
<td>Linux</td>
<td><code>.tar.gz</code></td>
<td><code>.tar.gz</code></td>
</tr>
</tbody>
</table>
<p>Note that on Linux, both binaries and sources should have the <code>.tar.gz</code> extension, but R and <code>renv</code> will handle this as appropriate during installation.</p>
